Study on the evaluate methods of head and hand influence on mobile antenna radiation performance

Abstract

The radiation performance of the terminal antennas is influenced by the head and hand of the person who is holding the device. At the antenna design phase, the performance reduction should be considered sufficiently in order to make sure the Total Radiated Power (TRP) and Total Radiated Sensitivity (TRS) of the terminal satisfy the requirement of the system. In this paper, an evaluate method of head and hand influence to the radiation performance of is illustrated, through which tolerance of the terminal antenna TRP/TRS decrease could be evaluated conveniently and efficiently.
